Sub-pixel transformations are operations where a pixel is moved a fraction of a pixel. You can't really do that, so you have to interpolate the data and every time you perform one of these operations you cut the resolution of your image data in half. So yes, the image will no longer show the effect of the barrel/pincushion distortion, but it will have taken a hit in the sharpness department. How big that hit is, depends on how sophisticated the filtering algorithms are in your software. There is no magic software bullet that will fix these problems. Software fixes like this aren't a substitute for a good lens. To quote my old boss: "You can't make chicken salad, out of chicken shit." Color correction is a whole different ballgame and is far less destructive than a transformation operation Feli
